Open Access Increases in scattered light causes increased darkness

What we see is not a simple consequence of the light sent to our eyes. Vision has two powerful spatial transformations of scene luminances: one optical; the other neural. The first spatial redistribution of light is intraocular scatter. Scattered light reduces the dynamic range of the retinal image compared to light from the scene. The second spatial transformation comes from neural processing that causes appearances to vary with the scene’s content. A beach scene, (mostly max-luminance scene elements, and maximal scattered light) has the highest slope neural response function. The post-quanta-catch neural mechanisms overcompensate for the intraocular scatter. Low-reflectance objects look darker in scenes with maximal scatter

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
